In build 0.70.2.66-git I have made the observation that in video filters if you select DXVA2 (native), it will display the expected NV12, 8 bit, 4:2:0 (DXVA2).
However, if you then change it to None, it continues to display NV12, 8 bit, 4:2:0 (DXVA2) even though software decoding should be in use at this point.
If you change it to DXVA2 (copy-back), it will display NV12, 8 bit, 4:2:0.
Then changing it to None, it displays NV12, 8 bit, 4:2:0.
Repeating the process where you go back to DXVA2 (native) and then None, None once again holds on to (DXVA2).
